Caves: Extreme Conditions for Life

open access: yes, 2016
For certain life forms on Earth, conditions that humans and other familiar organisms find hospitable can actually be deadly. Instead of a moderate climate with an atmosphere rich in nitrogen and oxygen, these organisms thrive in very hot or very cold ...

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

open access: yesAdvanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Dynamic Proton Activity Regulation via Brønsted Bases Enables Durable and High‐Energy‐Density Zn||MnO2 Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Our study demonstrates Brønsted base‐mediated proton transfer for HOAc dissociation regulation in weakly acidic electrolytes, where imidazole achieves optimal dynamic proton equilibrium‐simultaneously stabilizing Zn anodes and enabling efficient Mn2+/MnO2 conversion.

Dipole‐Engineered Conductive Additives for Ultrastable Interphase Evolution in High‐Areal‐Capacity Silicon Anodes

open access: yesAdvanced Functional Materials, EarlyView.
In the work reported herein, dipole‐engineered sulfonated carbon nanofibers enable conductive additives to actively regulate interphase formation in silicon anodes. Polar sulfonyl groups guide electrolyte decomposition to form a compact LiF‐rich interphase while promoting robust integration with silicon.

Trace Sulfur‐Doping Boosts NiCo Heterostructured Catalyst for Selective Glycerol‐to‐Formic Acid Electroreforming

open access: yesAdvanced Functional Materials, EarlyView.
A sulfur‐doped Ni–Co heterostructured catalyst is rationally designed to regulate interfacial electronic and adsorption properties for selective glycerol electrooxidation. The synergistic Ni–Co active sites promote hydroxide activation and glycerol adsorption, enabling efficient formic acid production and durable hydrogen generation under continuous ...
